[Pkg-xfce-devel] Bug#495707: segfaults when moving up directories too fast

[Jonny Lamb]

Package: thunar
Version: 0.9.0-10
Severity: normal

If one goes into a fairly deep directory tree and wants to get back a
known number of directories up, one can quickly click that many times on
the "go up a directory" button. However, if you press this at any
moderate speed, thunar segfaults.

This is easily reproducible by entering a deep directory structure and
clicking "up", "back" or "forward" relatively fast.

I installed thunar-dbg and ran it in gdb to give me a backtrace.
Hopefully it will be of some use:
